Develop a junction-level differential splicing frequency analysis method to sensitively detect alternative splicing alterations in Alzheimer's disease-associated genes.
Developed Differential Splicing Frequency Analysis (DSFA) to quantify RNA-seq reads at splicing junctions rather than whole genes, isoforms, or exons.
Re-analyzed published human and mouse RNA-seq datasets to examine splicing dynamics in Alzheimer's disease-associated genes.
Proposed U1 snRNA overexpression as a molecular strategy to alter targeted splicing frequencies in cellular and animal models.
Identified APP/58417N in humans and APP/52804N in mice as differentially expressed splicing junctions with significantly decreased frequencies across Alzheimer's disease datasets.
Associated splicing frequency reductions with decreased production of secretory amyloid precursor protein (APP), linking junction-level changes to disease onset or progression.
